Drilling by Robust Resources at the Perak Basin VMS target of the Romang Island project has revealed bonanza silver grades of up to 1825 grams/tonne. Each of the five diamond holes drilled at the target intersected precious metals and base metals.
Standout results have come from drilling on the western side of the Perak Basin. Two holes were drilled in this area and both intersected strong VMS exhalative mineralization, rich in silver and other metals.
One hole returned 7.4 metres from 12.6 metres @ 4.58 grams/tonne gold equivalent and 2.99% combined base metals (1.97 grams/tonne gold, 138 grams/tonne silver, 0.08% copper, 2.90% lead and 9.02% zinc). The other hole 80 metres to the southeast intersected 7.2 metres from 18.8 metres @ 14.1 grams/tonne gold equivalent and 5.56% combined base metals (0.77 grams/tonne gold, 707 grams/tonne silver, 0.14% copper, 3.11% lead and 2.41% zinc). This included a high-grade zone of 2 metres from 23 metres @ 34.84 grams/tonne gold equivalent and 14.0% combined base metals (0.41 grams/tonne gold, 1825 grams/tonne silver, 0.33% copper, 7.55% lead and 6.12% zinc).
These results, combined with previous results and geological logging of holes where assay results are awaited, indicate the western flank of the Perak Basin remains open for further discovery. Mineralization in the basin appears to strengthen towards the west under limestone cover. This is in keeping with the company’s mineralization model of basin-bounding faults acting as feeder zones for mineralization.
High grade manganese mineralization has also been discovered in the recent drilling round with two holes intersecting mineralized zones grading more than 40% manganese, including 1.4 metres from 6.5 metres @ 41.6% and 2.0 metres from 11 metres @ 42.6%.
Although the basin target remains open in all directions, recent drilling utilizing five company-owned diamond drill rigs, has mostly focused on infill pattern drilling for resource estimated purposes.
Drilling and data compilation remains on track for completion of a new Romang Island mineral resource estimate during the current quarter. Additional drilling to extend this resource will be the focus of the company’s 2014 drilling campaign.
An exploration target for the Perak Basin has been set at between 8-12 million tonnes of between 5% and 7% combined base metals, 1 and 2 grams/tonne gold and 60-80 grams/tonne silver for about 400,000-600,000 ounces of gold, 20-30 million ounces of silver and 1 to 1.5 billion pounds of base metals.
